NEW Pilot Frixion clicker is a truly unique type of gel rollerball, which erases cleanly, leaving no debris. This feat is achieved by the use of friction generated heat from rubbing with the pen"s rubber end stud. This is great as you do not need to carry around an ink-eradicator and re-writer. FriXion lets you write, erase and re-write, all with the same pen. Ink eradicators often leave a yellow watermark but FriXion erases cleanly. You can also write, erase and re-write over the same area as many times as you want. The pen features smooth gel ink to ensure a comfortable writing experience as the pen glides across the page. A non-slip rubber grip reduces writing fatigue. The pen is easily refillable with a twist-action barrel to replace the refill. The eraser avoids getting in the way of the retract mechanism, which is instead actuated by the pocket clip. Due to the erasable nature of the ink when exposed to strong heat, it is not recommended for use with legal documentation, signatures etc... Fine tip
